Initially I need to make it clear that I’m not promoting any products or services, just sharing what I’ve shared regarding prices and existing gear being reused. Moving forward... I own a T-Mobile 5G connection with a waveform FX3100 – definitely the “business” modem. It took me a lot of time and effort until it finally worked. At least, nowadays modems from X provider offer minimal features at best. We’ll discuss that later. The issue here is that the waveform provides terrible Wi-Fi, so I opted to use an Ex6250/Netgear as a mesh repeater – there’s only one available. The challenge is setting up an internal network. Of course, I need to organize my devices and assign them static IPs based on their V6 addresses, which I can manage easily on the waveform. Many of my gadgets are hardwired and pass through switches around my home. If they have an Ethernet port, they’re already connected. Once I get a stable connection, I’ll route them through the repeater (which is the only one). My main worry is the wireless equipment – the signal from the repeater is weak. That’s why I’m using it as a repeater. Well, not much. I can’t run nmap to find devices connected to this repeater! Thanks for the firewall – and considering its settings, they’re quite basic. There’s nothing about a firewall here, but nmap shows several ports being filtered. I can’t map out my setup on the extender. I’ve tried ddwrt, but it doesn’t have specific entries for my device or the repeater. My wireless gear is there, but I can’t locate any of them – printer, iPhone, girls’ iPhone, smart lights (1/2/3/4/5), Alexa, Google Nest thermostat. My subnet is 192.168.12.1/64, with 1 as the gateway or waveform address. I’d prefer a smaller range since I don’t have 254 devices – like comparing a Walmart lot to an Aldi lot. I need my gear in a dedicated area, almost like reserving a parking spot. Why? Because when I set up ADS I didn’t want the server to constantly look up every Wi-Fi device (using limited apps) and assign static IPs. DHCP is risky. So back to the main question: how do I disable the basic firewall on the extender? Even though the waveform lists 13 devices, I’m certain there are many more connected – my server alone has nine Ethernet ports, plus a TV, receiver, PlayStation, Raspberry Pi, PCs, DC0, DC1, DC2, and three switches. The math shows way more than 13. How can I map out the rest despite the firewall limitations? The smart lights and Nest thermostat are pretty basic – assigning static IPs isn’t feasible either. I’m stuck with a lot of devices I don’t know how to manage.
